Flawed logic, sorry.
You're comparing a pre-nerf BC instance with unequipped groups VS a post-nerf WOTLK instance with ubergeared groups facerolling trashes. At least if you want to do it right, compare pre nerf Mechanar + 16k hp tank with pre nerf HoR + 30k hp tank. Oh and, many of the HoR melee mobs (mercenaries and such) can one shot / 2 shots clothes two. So I guess that part of your argument fails too. If the healer doenst pay attention, with CC, a 30k HP tank can go VERY low VERY fast.

Then don't use the damn dungeon finder if you are such an "elitist". If you are striving for progression go do your dailies with your guildies, who have the same level of awesome gear than you do.
That way you can never be annoyed at doing something your greatself consider "not fun", while nobody is bloody forcing you to do it.
People have been calling you names and even if that could be seen as rude, considering the nonsense coming out of your mouth/fingertips it is soo justified it actually becomes polite.
In case you haven't noticed, WotLK is not serious business. At release I tanked heroic Naxx with 19K HP half a hour after I dinged to 80. The only difficulty was threat with my level 75 quest blue weapon.
